HARNESS STRAP.

Application filed September 29, 1927. Serial No. 222,837.

Myinvention relates to loom attachments and more particularly to the straps which are used for adjustably supporting the harness frames, and it is an object of the invention to provide harness straps which are.

more durable in construction and which will not stretch, all as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts, I

Figure 1 is a front elevation of part of a loom illustrating the application of my invention,

Figure 2, an enlarged front elevation of one of the straps,

Figure 3, an edge view, and

Figure 1, an enlarged rear. elevation of one of the straps.

In the drawings reference character 10 in dicates a pair of harness frames for supporting heddles 11, such frames being supported from harness rolls or sheaves 12 supported on a harness rod or shaft 18 by means of the harness straps which constitute the essence of my invention. The rolls or sheaves 12 are fixed upon the shaft 13 and the extremities of the harness straps are fixed to the rolls 12 whereby the oscillation of the shaft 11 will serve to alternately raise and lower the frames during the operation of the machine.

Each harness strap comprises a flexible tightly woven non-stretchable fabric end member 14k adapted to have its upper end securely fastened to one of theharness rolls 12 and having means for adjustably connecting its lower end to a hook 15 upon the barness frame 10. Said adjustable connecting means comprises a flat rigid bar 16 of strap iron or the like having its upper end perforated for the reception of a. bolt 1.7 which extends through the lower end of the fabric strap 14. The lower portion 18 of the strap iron bar 16 is provided with transverse serrations and with a longitudinally extending slot 19. A substantially U-shaped hookengaging member 20 is provided for cooperation with the serrated surfaces of the bar 16, said hook engaging member having one leg provided with a serrated end portion 21 and having its other leg provided" with a fiat portion having its extremity bent outwardly to form a finger piece 22 as shown, both of said legs being perforated for the reception of a bolt 23 and wing nut 2% by means of which the legs are clamped tightly to the serrated portion of the bar 16 in the desired position of relative adjustment.

On the side of the lower end of the fabric strap let opposite the bar 16 is secured, by

a finger piece 26 so that said finger piece and the finger piece 22 on the cooperating hook engaging member 20 may be grasped by the forefingerand thumb of the hand. the wing nut 2 1- is released the finger pieces 22 and 26 may be pressed toward each other anddthe harness strap correspondingly shortene A felt or rawhide insert 27 is preferably clamped between the legs of the U-shapcd member .20 about the upper portion of the hook 15. $uch insert serves as a bearing for the hook and prevents the wear which would be occasioned by the metal tometal contact. Also rust will not be discharged upon the harness and injury done to the cloth.

When

A harness strap of this character is less expensive to produce leather being dispensed with and such strap will wear substantially five times the length of the conventional leather strap. Also my strap will not stretch and cause the loom to make nus-picks but will maintain a uniform tension of the harness and after the warps change and the harness sets it is unnecessary to give any 7 1.

2. The combination of a hook for supporting aloom harness frame, a bar supporting said hook and having one end provided for adjustable connection with a cooperating bar, a fabric strap carried by said cooperating bar means for binding said cooperating bars together, and manipulating members carried by each of said bars whereby said members may be engaged by the finger and thumb and drawntogether for varying the length of the strap and consequently the tension upon the harness, substantially as set forth.

8. A harness strap for looms comprising a non-stretchableflexible strap, a rigid bar bolted to said strap and provided with serrations, a hook, a rigid bar supporting said hook and having serrations for cooperation with said strap whereby said bars may be adjustably connected, means for binding said serrated surfaces together, and oppositcly disposed manipulated portions carried by said bars and adapted to be engaged by the finger and thumb and drawn together for varying the adjustment between the rigid bars, substantially as set forth.

4;. A harness strap for loomscomprising a non-stretchable tightly Woven flexible end strap, a rigid bar bolted to said strap and having a serrated surface, a substantially U-shaped clamping member adjust-ably connected to said bar and having a serrated surface for cooperation with the serrated surface of the bar, means for clamping the legs of the U-shaped clamping member together for fastening the parts in fixed relation, and a harness engaging hook carried by said substantially U-shaped member, substantially as set forth.

5. A device of the class described comprising a flexible non-stretchable end piece, an attaching member, a strap connection for adju'stablyconnecting the end piece and attaching member comprising a bar having opposite'sides provided with serrated surfaces and second bar having portions resting against opposite sides of the first-bar, and being provided witlrserrations for engagement with the serrations onthe first bar, and

insane for clamping the members together,

substantially as set forth. 7
